The bike, officially named the Transition Spindledog, was nicknamed the "Grim Donut" due to its outrageous appearance and a paint job featuring sprinkles. The geometry was baffling:

The "Pinkbike Grim Donut" refers to a radical mountain bike prototype series developed by Pinkbike to mockingly skip current design trends and leap straight to the "geometry of 2030". Initially conceived as an April Fool's joke, it evolved into a multi-part video series and a legitimate performance experiment. The Prototype Series
